Petunia plant named ‘Duepetsurwhiorch’

ABSTRACT

A new and distinct cultivar of  Petunia  plant named ‘Duepetsurwhiorch’, characterized by its mounding to trailing plant habit; vigorous growth habit; freely branching habit; early and freely flowering habit; light red purple-colored flowers with purple-colored throats; and good garden performance.

Botanical designation: Petunia×hybrida.

Cultivar denomination: ‘DUEPETSURWHIORCH’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Petuniaplant, botanically known as Petunia×hybrida and hereinafter referred toby the name ‘Duepetsurwhiorch’.

The new Petunia plant is a product of a planned breeding programconducted by the Inventor in Rheinberg, Germany. The objective of thebreeding program is to create new vigorous and early-flowering Petuniaplants with numerous attractive flowers.

The new Petunia plant originated from a cross-pollination made by theInventor in July, 2014 in Rheinberg, Germany of a proprietary selectionof Petunia×hybrida identified as code number TT13-005734-009, notpatented, as the female, or seed, parent with a proprietary selection ofPetunia×hybrida identified as code number TT13-002268-001, not patented,as the male, or pollen, parent. The new Petunia plant was discovered andselected by the Inventor as a single flowering plant from within theprogeny of the stated cross-pollination in a controlled greenhouseenvironment in Rheinberg, Germany in May, 2016.

Asexual reproduction of the new Petunia plant by terminal cuttings in acontrolled greenhouse environment in Rheinberg, Germany since June, 2016has shown that the unique features of this new Petunia plant are stableand reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Petunia have not been observed under all possiblecombinations of environmental conditions and cultural practices. Thephenotype may vary somewhat with variations in environmental conditionssuch as temperature and light intensity without, however, any variancein genotype.

The following traits have been repeatedly observed and are determined tobe the unique characteristics of ‘Duepetsurwhiorch’. Thesecharacteristics in combination distinguish ‘Duepetsurwhiorch’ as a newand distinct Petunia plant:

-   -   1. Mounding to trailing plant habit.    -   2. Vigorous growth habit.    -   3. Freely branching habit.    -   4. Early and freely flowering habit.    -   5. Light red purple-colored flowers with purple-colored throats.    -   6. Good garden performance.

Plants of the new Petunia can be compared to plants of the female parentselection. Plants of the new Petunia differ primarily from plants of thefemale parent selection in flower color as plants of the female parentselection have bluish purple-colored flowers.

Plants of the new Petunia can be compared to plants of the male parentselection. Plants of the new Petunia differ primarily from plants of themale parent selection in growth habit as plants of the new Petunia aremore compact than plants of the male parent selection. In addition,plants of the new Petunia and the male parent selection differ in flowercolor as plants of the male parent selection have pinkish purple-coloredflowers.

Plants of the new Petunia can be compared to plants of Petunia×hybrida‘Sunsurfsirou’, disclosed in U.S. Plant Pat. No. 24,453. Plants of thenew Petunia and ‘Sunsurfsirou’ differ primarily in the followingcharacteristics:

-   -   1. Plants of the new Petunia are more compact than plants of        ‘Sunsurfsirou’.    -   2. Plants of the new Petunia are more freely flowering than        plants of ‘Sunsurfsirou’.    -   3. Plants of the new Petunia flower earlier than plants of        ‘Sunsurfsirou’.    -   4. Plants of the new Petunia have larger flowers than plants of        ‘Sunsurfsirou’.    -   5. Plants of the new Petunia and ‘Sunsurfsirou’ differ in flower        color as plants of ‘Sunsurfsirou’ have white-colored flowers        with light yellow green-colored venation.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurementsand values describe plants grown during the summer in 22-cm containersin a glass-covered greenhouse in Rheinberg, Germany and under culturalpractices typical of commercial Petunia production. During theproduction of the plants, day and night temperatures averaged 18° C. andlight levels averaged 4,500 lux. Plants were 13 weeks old when thephotograph and description were taken. In the following description,color references are made to The Royal Horticultural Society ColourChart, 2007 Edition, except where general terms of ordinary dictionarysignificance are used.
